This is a study on ideological initiation (vikalpita), which is one of the two initiating patterns of grasping on the self and phenomena, along with the defiled and cognitive obstructions then caused, according to Cheung Wei Shih Lun. "Ideological Initiation" is addressed in this article to restore its importance from the long-term underestimate in the doctrinal studies. The underestimate is due to the assumption that if compare with the role of inborn initiation (sahaja) of grasping and obstructions, the ideological initiation seems as-if less damage than the inborn initiation, for it can be removed much earlier and easier than the latter on the path of spiritual cultivation. The article is composed of following sections: firstly, definition of ideological initiation; secondly, the co-relationship between ideological initiation and defiled mental factors (especially five wrong views); thirdly, further analysis on ideological initiation, in contrast with its inborn counterpart. Finally, is the conclusion.
